You can put this solution on YOUR website!
Let the first side be x, the third side be y, and the longest side be z
\n" ); document.write( "so you have the first side is half the longest side ==> \"x+=+z%2F2\"
\n" ); document.write( "then you have the third side is 12 feet less than the longest side => \"y+=+z+-12\"
\n" ); document.write( "Then you have x + y + z = 53 because 53 is the perimeter
\n" ); document.write( "that means \"+z%2F2+%2B+z+-+12+%2B+z+=+53\"
\n" ); document.write( "\"z%2F2+%2B+2z+=+65\"
\n" ); document.write( "\"z+%2B+4z+=+130\"
\n" ); document.write( "\"5z+=+130\"
\n" ); document.write( "\"z+=+26\"
\n" ); document.write( "So now you have z = 26
\n" ); document.write( "\"x+=+z%2F2+=+26%2F2+=+13\"
\n" ); document.write( "\"y+=+z+-+12+=+26+-+12+=+14\"
\n" ); document.write( "SO there are your three sides
\n" ); document.write( "TA-DAH
